Rosetta Results: Comets "Did Not Bring Water To Earth"

Posted by samzenpus on from the wet-of-space dept.

An anonymous reader writes with findings from the Rosetta mission which suggests water on Earth probably came from asteroids, and not comets."Scientists have dealt a blow to the theory that most water on Earth came from comets. Results from Europe's Rosetta mission, which made history by landing on Comet 67P in November, shows the water on the icy mass is unlike that on our planet. The results are published in the journal Science. The authors conclude it is more likely that the water came from asteroids, but other scientists say more data is needed before comets can be ruled out."

    They got it wrong. The dry comets are lighter and so are still flying around. The wet ones were heavier and so fell to Earth.

      Someone mod him down.... if you're in orbit... mass has nothing to do with it.

      That whooshing sound you heard was not a comet passing over your head, it was the joke.

      Someone mod this guy down too... there is no air in space and hence no sound... there is therefore no "whooshing" sound.

    God damn it, another drug scandal for planets. Some of the dwarf planets used ass steroids to get bigger and now they are real planets. But it caused them to be covered with a lot of water. Figures...
